Each time I have deleted an LV on LVM2 on 2.6, it has corrupted my
metadata. Last time I did a vgcfgrestore on 2.4 and it worked, however I
have recently been bitten by some sort of incompatibility bug and my LVM
now only works on 2.6 (it might work on a 2.4+devmapper kernel, I'll
look into that). Here is what happens when I try to get my metadata
back:
root@amphibian:/usr/src/linux# vgdisplay -d -v
Finding all volume groups
Finding volume group "vg-big"
invalid lv in extent map
Couldn't fill logical volume maps.
Volume group "vg-big" doesn't exist
root@amphibian:/usr/src/linux# pvscan -d -v
Wiping cache of LVM-capable devices
Wiping internal cache
Walking through all physical volumes
invalid lv in extent map
Couldn't fill logical volume maps.
No matching physical volumes found
root@amphibian:/usr/src/linux# vgcfgrestore -v -d vg-big
PV /dev/hda is a different format (lvm1)
Restore failed.
That last one is particularly perverse; I was always told that LVM1 and
LVM2 are compatible. Of course later I discovered this not to be the
case; after some operation or other (creating an LV? resizing one?) on
LVM on 2.6, I could no longer access my LVs under 2.4/LVM1.
Any help?
